Goals: (1) to explore the hilly upland Fra Mauro region of the moon; (2) to perform selenological inspection, survey and sampling of material in the Fra Mauro formation; (3) to deploy and activate an Apollo lunar-surface experiments package (ALSEP); (4) to further develop man's capability to work in the lunar environment; and (5) to obtain photographs of candidate lunar exploration sites.

Accomplishments: Apollo 13 was supposed to land in the Fra Mauro area of the moon. An explosion on board forced Apollo 13 to circle the moon without landing. The astronauts returned to the Earth without any loss of life.

The astronauts did take photographs of the moon while rounding it to return to the Earth. Also, the upper stage of the launch vehicle impacted the lunar surface as intended to calibrate seismometers installed by Apollo 11 and 12.

Apollo 13 astronauts could have died from their own exhaled carbon dioxide. (There was not enough lithium hydroxide canisters to fit the round openings in the lunar module; that is until a quick fix was found.

The lunar-module lifeboat could not survive re-entry into Earth's atmosphere, so the astronauts had to move back into the command module for the final part of their return home.
